In some conditions, may I use an @ character instead of using the longer isset() function?
If not, why not?
I like to use this because in a lot cases I can save several quotation marks, brackets and dots.
I assume you’re talking about the error suppression operator when you say
@character, but that isn’t a replacement forisset().isset()is used to determine whether or not a given variable already exists within a program, to determine if it’s safe to use that variable.What I suspect you’re doing is trying to use the variable regardless of its existance, but supressing any errors that may come from that. Using the
@operator at the beginning of a line tells PHP to ignore any errors and not to report it.The
@operator is shorthand for “temporarily seterror_reporting(0)for this expression”.isset()is a completely different construct.
